If the LSP changes, the label and interface information displayed when you issued the
ping command continues to be used. You must configure MPLS at the
hierarchy level on the remote router or switch to ping an LSP terminating there.
mpls]
You must configure MPLS even if you intend to ping only LDP forwarding equivalence
classes (FECs).
You can configure the ping interval for the
time in seconds using the
hierarchy level. For more information, see the Junos OS MPLS Applications Configuration
Guide.
In asymmetric MTU scenarios, the echo response may be dropped. For example, if the
MTU from System A to System B is 1000 bytes, the MTU from System B to System A is
500 bytes, and the ping request packet size is 1000 bytes, the echo response is dropped
because the PAD TLV is included in the echo response, making it too large.
